I need to connect an ADC0803LCN (CMOS) to PC LPT1.(TTL)

My question is: should I need a resistors or some kind of interface (CMOS to TTL "for Data")& (TTL to CMOS " for Commands").

thanks .....

Dear Khaled,

As far as i know the LPT is capable of handling TTL level voltages,
but you should protect your port by a proper means of isolation not to burn the motherboard or the port.
